Old 1920's Convectors

I am trying to calculate the connected EDR of some convectors. The elements look to be made of brass. The tubes are oval shaped with brass fins and brass ends. They sorta remind me of a car radiator.

Any idea where I could find reference material for these 1920's convectors?

    It pays to wander off the Wall:

    Here you will find convectors made by American-Standard, Herman Nelson, Trane and others.

    If what you want isn't there, get a copy of Dan's book "E.D.R." which has many more listings.

    Do you have Dan's book "Every darn Radiator" You can buy it on the store, on this site. If you can post a picture, we may be able to help you too.
